2017 Statewide Winter Storms SITUATION SUMMARY Cal OES Coastal Region Paul s Slide, State Route 1, Monterey County Per Cal OES Coastal Duty Officer (CDO), as of 1300 hours on 05/25/17, Paul s Slide on State Route 1 has been closed to all traffic. Caltrans engineers report slide activity and the area has been closed in the interest of public safety. Assessment will commence and further details will be provided once released. State Route 1 opened briefly on 06/02/17 for locals and delivery access. Full closure resumed the evening of 06/02/17 through Tuesday 06/06/17 in the evening. Mud Creek Slide, State Route 1, Monterey County The Mud Creek area on State Route 1 sustained a major slide on the evening of 05/20/17, when over a million tons of rock and dirt fell down the slope continuing down to the ocean floor 250 feet off the shoreline. The Mud Creek area is ¼ mile in length, made up of five slides, four of which fell during this single incident and consolidated into one slide. The remaining slide now extends 1,500 feet in length over State Route 1 and is about 35 to 40 feet deep. Roadwork at Mud Creek was suspended and heavy equipment removed last week due to the threat of new slides and for safety of highway workers. Caltrans geologists and engineers plan to assess it further when this area stabilizes. There is no estimate when this section of State Route 1, approximately nine miles north of the San Luis Obispo/Monterey County line will reopen. Pfeiffer Bridge Incident, Monterey County California Highway Patrol (CHP) and Caltrans had a hard closure on the Pfeiffer Bridge on HWY 1 at mile marker 45.52 (SB Sycamore Canyon and the Bridge) due to a crack in the bridge. The bridge has been demolished so the road is closed and estimates for some access from the north is late September 2017. Backup air medical transport plans have been developed for medical emergencies through Cal OES Law Enforcement Branch. All businesses north of the Pfeiffer Canyon Bridge closure are open to the public. 4

WEATHER OF CONCERN Weather of Concern Wet weather returns to Northern California starting Wednesday evening, with precipitation spreading across the area by Thursday afternoon and continuing through Friday. Confidence continues to improve that this will be relatively wet system for June, with Thursday possibly the second or third wettest on record for the date for some locations. Possible afternoon thunderstorms on Friday.

WEATHER SYNOPSIS BY REGION NORTHERN CALIFORNIA There won't be much apparent change in the weather today from yesterday as warm, dry weather continues. Wednesday will be a bit cooler as a low pressure trough off the coast moves our way. The big change in weather pattern will come later Wednesday as that trough arrives at the coast. It will be moving ashore Thursday with quite a bit of rain developing over all areas of the Northern California region starting late Wednesday evening at the coast and spreading inland overnight and Thursday. Wetting rain (0.10") will be possible in most areas with many locations west of the Cascade/Sierra crest receiving quite a bit more than that. Some showers will be lingering in the northern and eastern areas Friday and Saturday as well. Higher pressure with dry, warming conditions will return Sunday. There will be some gusty S to SW winds develop Wednesday afternoon as the system approaches followed by a chance of gusty northerly winds developing late in the weekend. Temperatures will be in the low and mid 90s again today in the warmest inland areas then plummet Thursday to around 70, which will be as much as 15-18 degrees below seasonal normals there. Temperatures will be slow to warm up until early next week. SOUTHERN CALIFORNIA The pattern of warm and dry conditions inland with marine layer coverage near the coast will continue through Wednesday. Temperatures have been near, to a bit above, normal across areas inland and above the marine layer with some valleys reaching the lower 90s the past two days. Minimum RH above 5,000 feet will drop into the 8-12% range today and Wednesday across Southern California. An unseasonably deep trough will plow into the Pacific Northwest later this week which will result in much cooler weather, particularly to the inland valleys of the central part of the state. By Friday, high temperatures will be 10-15 degrees cooler with valley readings only in the upper 70s to lower 80s. Southwest winds will begin to increase in and near the deserts Wednesday afternoon, possibly reaching speeds of 20-30 mph with higher gusts by Thursday and Friday. There is a chance of some light shower activity across Yosemite N.P. Thursday and Thursday night, but most of the precipitation associated with this system will remain to our north. Cool, breezy weather will last through Saturday before a warming trend begins early next week. 10
